5. Telecontrol and Two-Way Audio
The iConnect Control System offers a range of Telecontrol features that provide remote access via the telephone.
These features include Two-Way Audio, remote arming/disarming and cancel siren activation. This chapter explains
these features and their operating procedures.
Telecontrol features can be separated into two fundamental groups; incoming and outgoing calls. These groups differ in
their associated features.
5.1. Incoming Calls
The Control System can receive incoming calls from either the user or central station operator. Users may use this
feature as a convenient way of contacting their family, operating their system or to check their home when they are
away. Additionally, the monitoring service can contact the user in the event of an emergency or use this feature for
listen-in alarm verification.
For any of the incoming Telecontrol features to function, Telecontrol must be enabled in the Communication Options
section of the Programming menu – see p. 61,
10.6.8 Incoming Calls.
5.1.1. User Code Verification
To prevent unauthorized attempts to connect with the Control System, there are two user codes designed for use with
the Telecontrol features. The Telecontrol code enables the user to establish communication with the Control System at
any time. Additionally, the Central Station TWA Code is used exclusively for Two-Way Audio alarm verification and is
only valid for a ten-minute period following an alarm – see p. 21,
4.4 User Codes.
5.1.2. Incoming Calls via PSTN
In the case of PSTN communication, the Control System often shares a line with regular telephone handsets, an
answering machine or a fax machine. It is therefore important that the Control System distinguish between calls so that
it knows when to pick up the relevant call. For this purpose the iConnect Control System employs a double call
method.
To connect to the Control System using the double call method:
1.
Dial the telephone number of the line connected to the Control System.
2. Wait for two or three rings and hang-up.
3. Wait at least five seconds and dial the number again; on the second ring, the Control System picks up and sounds
two DTMF tones.
5.1.3. Incoming Calls via a Cellular Network
The Cellular Communication module has its own individual telephone number and therefore, the double call method is
not needed. In this case, the user or central station operator may call the Control System directly.
5.1.4. Telecontrol Call Procedure
The following procedure explains how to make a Telecontrol call. The conditions and procedure differ when using
PSTN or Cellular Communication. For further information, see the entire section
5.1 Incoming Calls.
To make a Telecontrol call:
1.
Call the Control System either using the double call method (PSTN) or directly (Cellular/PSTN); when the
Control System picks up, two DTMF tones are sounded.
2. Enter the Telecontrol code (Code 29) on your telephone within 15 seconds.
Do not enter your user code until you hear the two DTMF tones. Any digits entered before
the tones are sounded are disregarded by the system.
3. A DTMF tone is sounded to indicate that the system is ready to receive commands.
The following DTMF commands are available:
o
Press "2" for Two-Way Audio.
If the TWA mode is defined as "Simplex" (see p. 61, 10.6.11, TWA Mode.), the audio channel opens in
Listen mode (microphone active/speaker mute). To switch to Speak mode, press "1" on your telephone.
To switch back to Listen mode, press "0" on your telephone.
